Other questions
Entries run from 1 November 2026 at 00:00 to 8 December 2026 at 23:59. Entry closes early if the field fills within that period, so it is worth entering as soon as you are ready.
The race uses the RUN PASSPORT smart reception system, so no number-card voucher is posted. When your ticket is ready you will be notified at the email address registered with your RUNNET account. Download the participation ticket from the emailed link and either save it on your smartphone or print the PDF and bring it to the venue. The sending address is [email protected].
Reception is at the Isehara Elementary School ground, 4-1-1 Isehara, Isehara City, and opens at 7:20. Reception stays open until about 90 minutes before each wave start, so arrive well before your own start time.
The cable car and bus from the finish area down to Isehara Station are free for runners. Boarding instructions are sent out with the participant information.
The race is cancelled if an earthquake of seismic intensity 5-lower or greater occurs or is predicted. This is a mountain course, so the organisers take that risk seriously.
